IMPROVED PROCESS FOR LINING OlL-BARRELS.

Specification forming part of LettersPatent No. 48.625, dated July 4,1865.

To allwhom it may concern:

Be it known that I, CHARLES B. I-1Uron1N- SON, of Aubnrn,-in the countyof Cayuga and State of New York, have invented a new and ImprovedProcess for Applying Air-Tight Solutions'tothe Interior of Oasks,Barrels, 820.;- and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had tothe-accompanying drawings, forming part of this specification,in whichFigure l is a vertical central section of the means employed forcarrying out my invention 'Fig. 2, a horizontal section of the same,taken in the line as a, Fig. 1. I

Similar letters of reference indicate correspending parts.

This invention relates to a new and improved mode for applying solutionsto the interior of casks, barrels, 860., for the purpose of renderingthem perfectly tight iuorder to prevent leakage and the evaporation oftheir contents. {:The invention is applicable to barrels or casks yforholding coal-oil, turpentine, and all volatile in a warm, liquid state,is poured into the cask or barrel and the latter turned, so that itsinterior surface will be perfectly coated, and the hot air is againforced into the cask or barrel, and by means of pressure forces thesolution into the open pores of the wgod and into every crevice andcrack, the hot air at the same time keeping the solution warm andliquid, so thatthe pressure to which it is subjected will cause it toeffectually close every opening and render the interior surface of thebarrel or cask perfectly tight.

I will now proceed to describe the means I employ for carrying out myinvention, although ing with the air-pump. In the lower part of thiscylinder there is a lire-grate, O, and in the upper part of saidcylinder, above the fire-grate, there is placed an air-heatin g chamber, D, h aving a safety-valva'E, at its upper end. This chamber Dcommunicates with the space I) by means of a pipe, F, which enters theupper part of D and extends down within'it to its lower end, as shownclearly in Fig. 1, and the upper part of said chamber has a pipe, G,communicating with it, which passes out through the side of thecylinder, and when the device is in operation is inserted in the cask orbarrel being operated upon. This cask or barrel is shown in red in Fig.1.

I will no w proceed to describe the operation.

The pipe G is inserted in the bung-hole of the'cask or barrel, but nottightly. If tight therein, a vent should be in the cask or barrel. Thefire is then made in the cylinder A, and when sufficiently under wayair, by means of the pump B, is forced into space I) and up through saidspace into pipe F, and thence into the lower part of chamber D and outthrough pipe G into the cask or barrel. This air, which in its passageup space I) and through chamber D becomes heated, forces, underpressure, the cold air out from the cask or barrel, and the vent oropening in the cask or barrel is then closed and the pipe Gr closelyfitted in the bun g-hole, so as to prevent leakage around The hot air isthen again forced into the cask or barrel and the interior of the latterwarmed or heated, so that the pores-of the wood will be opened, the hotair, under pressure, penetrating into every crack or crevice, and actingin the most eflicient manner to effect this'end. After the interior ofthe cask or barrel is thus thoroughly warmed, dried, and the pores ofthe wood opened the cask or barrel is detached from pipe G and thesolution poured into it and the cask tor barrel turned, so that itsinterior will be thoroughly coated.

The pipe G is then inserted tightly in the bunghole and hot air againforced into the cask or barrel, which keeps the solution warm and fluid,and, owing to the pressure of the pump, drives or forces the solutioninto the open pores of the wood and into every crack and crevice, cansing the interior of the cask or barrel to be perfectly coated and everycrack closed, so as to effectually prevent leakage and evaporation.

I would remark that, it necessary or desired, the space 11 between theWalls a a, may be filled with sand, metal filings, or other suitablematerial to'inore rapidly heat the air by causing thelatter to bebrought in contact with agreater area of heated surface, and the chamberD may also be supplied with a similar material for a like purpose.

As before stated, I donot confine myself to theprecise means hereindescribed for carrying out my invention, as that may be modified thenapplying the solution to the interior warm surface of the cask or barreland forcing it into the open pores, cracks, and crevices by hot airunder pressure substantially as set forth.
